Answer:
The bimetallic strip will bend to the iron's way since
When heated copper expands more than iron
Explanation:
bimetallic strips are temperature regulatory devices used to convert a temperature change into mechanical displacement.
It consists of two layers, usually iron and copper which layers are joined together to form the strip owing to the difference in the constants of expansion of the two materials, a flat strip will bend one way (toward the iron part) if heated. The linear thermal expansion coefficient relates the change in temperature to the change in a material's linear dimensions.

Explanation:
Sound waves are often simplified to a description in terms of sinusoidal plane waves, which are characterized by these generic properties:
Frequency, or its inverse, wavelength.
Amplitude, sound pressure or Intensity.
Speed of sound.
Direction.
Answer:
Rarefaction is the reduction of an item's density, the opposite of compression. Like compression, which can travel in waves, rarefaction waves also exist in nature. A common rarefaction wave is the area of low relative pressure following a shock wave.
